Research progress on advanced carbon fiber reinforced composite honeycomb structures

Carbon fiber reinforced composite honeycomb (CFRCH) materials have attracted more and more attention due to their unique properties in aerospace, automobile manufacturing and other industries. The research on this high-performance composite material is also deepening, covering many aspects such as structural optimization, manufacturing process and mechanical properties. Therefore, it is necessary to systematically review the existing research results and analyze their development trends and challenges in order to promote their further development. The article explores several innovative designs, including negative Poisson’s ratio (NPR) structures, biomimetic gradient designs, filler designs, and more, which improve the impact resistance and energy absorption efficiency of materials through special deformation mechanisms or inspiration from natural structures. At the same time, the application of 3D printing technology, vacuum-assisted resin molding, and multi-process composite technology in CFRCH preparation is introduced, emphasizing the importance of these advances for the realization of high-performance composite materials.
